(A) The epicardial PEF catheter with multiple electrodes is shown exiting the cinching tool. (B) The fluoroscopic image demonstrates proper positioning of the ablation catheter electrodes en bloc around the 4 PVs and posterior LA. A pulmonary artery catheter and coronary sinus catheter are in place. (C) The PEF application between a single pair of electrodes (green arrow) during sequential activation around the entire loop to complete a full ablation sequence. (D) The pericardial reflections and sinuses as seen with the heart removed. The ablation catheter is positioned encircling the posterior LA and the 4 PVs. Abbreviations as in Figure 1.
